Web Crippling And Combined Web Crippling And Bending Of Steel Decks, Wei-Wen Yu
CCFSS Library (1939 - present)
INTRODUCTION A. General During the period of October 1968 through September 1980, the 1968 Edition of the AISI Specification was used for the design of steel deck webs that could withstand web crippling and combined web crippling and bending. (1) The design formulas used to prevent web crippling were developed primarily on the basis of tests conducted in the 1940's and 1950's at Cornell University. (2-4) Recently, new types of cold-formed steel sections have been developed and used in building construction. The use of unusual geometric configurations has complicated the design of such members. In order to develop new design …

Behavior Of C- And Z-Purlins Under Wind Uplift, Parviz Soroushian, Teoman Peköz
CCFSS Library (1939 - present)
INTRODUCTION Cold-formed steel lipped channel (C-) and Z-purlins are used widely in the roofs of metal buildings. They are easy and economical to fabricate and erect. However these sections are weak in the lateral direction and in torsion. In order to use their full bending capacity in the strong direction, they must be braced in the lateral direction and against twisting. Roof panels which are connected to the purlins do provide to some extent such bracing effect by virtue of their shear rigidity and resistance to local bending at the connections. Wind uplift is an important design condition for roof …

The Strength Of Cold-Formed Steel Columns, Du Thinh Dat, Teoman Peköz
CCFSS Library (1939 - present)
INTRODUCTION The flexural buckling of columns is a fundamental problem whose solution was found by Euler more than 200 years ago. Since then, refinements have extended the solution to the inelastic range and clarified the influence of initial deflections and residual stresses. Most of these advances were made by studying hot-rolled steel columns, which are widely used. Cold-formed sections are coming into greater and greater use, thanks to the great variety of geometries available, which make them suitable for specific needs, and the significant advances made in the last four decades in understanding the behavior of cold-formed steel and in …

Ultimate Strength Of Cold-Formed Steel Z-Purlins, M. A. A. Razak, Teoman Peköz
CCFSS Library (1939 - present)
INTRODUCTION Cold-formed steel structures are being widely used in various forms of construction such as industrial plants, gymnasiums, hangars and metal buildings. One important feature of metal building construction is the use of light gage roof panels connected to purlins, particularly of the Z-section. This section is, besides the channel-section, the simplest two-flange section which can be produced by cold-forming. The purlins have span lengths of 20 to 25 feet, generally made continuous over the building rigid frames by nesting. Construction details vary from manufacturer to manufacturer. The purlins available would typically have prepunched holes for connection of various types …

INTRODUCTION In the design of steel buildings, the "Allowable Stress Criteria" have long been used for the design of cold-formed steel structural members in the United States (1), Canada (2) and other countries (3). Even though the theoretical concepts of risk and reliability analyses have been available for some time (8-10) and the slgnlflcance of such concepts in structural safety and design is well recognized, the probabilistic method has not been explicitly adopted as a basis for the American design standard for steel structures. In view of the fact that the mathematical theory of probability, which has been so successfully …

Non-Linear Finite Element Analysis Of Light Gage Steel Shear Diaphragms, Erdal Atrek, Arthur H. Nilson
CCFSS Library (1939 - present)
SUMMARY Shear diaphragm action of properly designed light gage steel panels used for floors, roofs, and walls in steel buildings increase the stiffness and strength of such buildings. Considerable savings in weight and cost can be realized if full account of this action is taken in design. To make good use of the diaphragm action, detailed knowledge on diaphragm response to loading is essential. An efficient computer program has been prepared to analyze light gage steel shear diaphragm behavior in the linear and nonlinear ranges of response, up to collapse. The program uses figinite element concepts for analysis, and has …

Mechanical Connections In Cold-Formed Steel: Comprehensive Test Procedures And Evaluation Methods, John Fraczek, George Winter, Teoman Peköz
CCFSS Library (1939 - present)
Design equations do not exist for connections in cold-formed steel formed with most types of mechanical fasteners, and such designs are presently based on test results. A lack of standard test procedures and corresponding evaluation methods impedes the acceptance of connection designs and the exchange of information vital to understanding the connection performance of a large number of mechanical fasteners with diverse properties. Initial steps toward standardization are taken with the development of fixtures and procedures for single shear, pullout and pull-over tests. The proposed single shear tests employ both a simple specimen formed with two overlapping straps and a …
